Hopefully you do understand the difference of a scientist getting attacked either because the scientific study he (or she) has made and/or the conclusions the scientist has made from the study and being attacked because publicly wearing a babe-shirt is offensive to some. There is a difference in the seriousness of the matter. Sticking to the trivial can be counterproductive.a university president or Nobel Laureate may be publicly chastised and even asked to resign for discussing hypotheses that are deemed politically incorrect. — NOS4A2
It's more important when actual scientific research is compromised or altered because of political correctness or political ideology, even if science has to deal with ethical questions. And there's a short distance from scientific ethics to political correctness or political ideology.this is important and not as dumb as you pretend. — NOS4A2

Exactly.Talk about thread-drift. — John Gill
In my view comments about a shirt as an example of the effect of political correctness on science is itself dumbing down the issue. It's as far fetched as the tweets saying that the shirt shows how hostile STEM field is towards women.Perhaps it’s not high-brow enough for you. But I think that because it dumbs down public discourse is one of the reasons it should be opposed. I was only trying to give some examples. - What I’m trying to argue is that we should resist the pressure on science to conform to a limited, ever-changing and infantilizing lexicon of speech, in this case the lexicon of the politically correct. I’ve already given examples and shared the concurring arguments of others to give force to the argument. — NOS4A2

This is the interesting question.The only question now is whether this maneuvering will more energize the left or the right in the upcoming election. It's doubtful it will change a single vote from one side to the next, but it might cause more people to go to the polls. — Hanover
Your reasoning of it being an conjecture or an informal intuition can be done only in hindsight. The definition of an axiom is "A self evident proposition requiring no formal demonstration to prove its truth, but received and assentedYou put 'axiom' in inverted commas for good reason, even if you didn't understand it. That all numbers are rational wasn't an axiom - it was a definition, an informal intuition, or a conjecture, depending on how they approached numbers in their thinking. — SophistiCat
Yet what you are stating is a philosophical view of mathematics. What you are basically saying is that: "You cannot win this debate because you don't accept formalism!"And I gave you an example where three different, consistent mathematics have been created based on three different axioms that contradict each other. The point is that neither mathematics, nor the axioms any specific field of mathematics is based on, are intended to represent absolute truth. You cannot win this debate with a nonsense claim like "the axiom is wrong." — JeffJo

I already gave an example of what was thought to be an axiom that wasn't. Greeks thought that all numbers were commensurable. The thought was for them self evident: math was so beautiful and harmonious. Yet all numbers weren't commensurable.There exists irrational numbers (and even transcendental numbers). What we had accepted to be true wasn't the case.My point is that they can't. That's why they are axioms. — JeffJo
Political correctness is used as a pejorative, yes. But it does also mean that language or policies are used with the intention to avoid offense or disadvantage to members of particular groups in society. Or then in a more general definition: something that is correct from a certain political viewpoint, but not universally accepted to be so.Political correctness has been derided by pundits from all over the spectrum. — NOS4A2
Sure. I'll disagree with you on this matter and try to argue my point.1) If a scientific fact was politically explosive, would obscuring it be justified? (Could political correctness ever take precedence over scientific truth?)
2) Is there any specific instance of a scientific fact where this has taken place?
I would lean 'no' on the first one, but it's a very thorny issue. On 2) I believe the answer currently is 'no'.
So, what I would ask of you is can you find a specific instance where you can demonstrate the answer to 2) is 'yes' and do you have an unequivocal position on 1)? — Baden
In November 2018, media from all over the world reported that two twin girls had been born with modified genes to make them HIV immune. Their birth was the result of an ‘experiment' (presently it can only be called that) conducted by He Jiankui with couples in which the males were HIV carriers. Using CRISPR technology to immunise the babies against the HIV virus, He Jiankui managed to disable the CCR5 gene that enables the HIV infection (although he still did not present complete evidence of this achievement).
The Sokal affair is more about lax scientific standards. He makes his argument even more clear in his book "Fashionable nonsense".My point is that science should remain ideology-free and scientists should have free reign to use the words they see fit. The threat from the religious is well-known and hardly warrants discussion, but the threat from the post-modernists and constructivists is becoming more apparent.
The Sokal affair is an example, but also the cancelling of Nobel Laureate Timothy Hunt proves pressure can result in loss of employment and social ostracism. — NOS4A2
Can you have a look at what I said below. It seems wrong and right.
n(set of natural numbers) - n(set of even numbers) = infinity - infinity = zero because both are, well, infinite.
— TheMadFool
Consider two infinite sets A and B of equal cardinality i.e. n(A) = n(B) = infinity
Shouldn't n(A) - n(B) = 0?
Yet n(set of natural numbers, infinite) - n(set of even numbers, infinite) = n(set of odd numbers, infinite) which is infinite indicating that infinity - infinity = infinity — TheMadFool
I guess you didn't participate in the Decolonizing Science? thread. :wink:Such as... ? Where's the broad PC attack on science that we need to worry about going on? The only serious attacks on science I'm aware of are from the right. — Baden

I don't recall this from studying economics in the university. I thought the one they put on the pedestal was the consumer that optimizes his or her well being.The value of a human being is the product of his labour; such has been the orthodoxy of economics, — unenlightened
When you can laugh off things, things are good. But in the example I gave Blair wasn't laughing it off. And this was just one issue from many.Yes of course, but I don't know if you were aware, there is an equally pervasive issue with Islamophobia in the Tory party and opposition MPs repeatedly called this out, but it didn't cut through in the media and was repeatedly laughed off by Tory politicians. While the media couldn't stop talking about the media circus they had created around anti semitism in the Labour Party. — Punshhh
My point was that axioms can be possibly false. Our understanding can change. Best example of this was that until some Greeks found it not to be true, people earlier thought that all numbers are rational. Yet once when you prove there are irrational numbers, then the 'axiom' of all numbers being rational is shown not to be true.With all due respect, if you want "actual truth", then you do not understand the purpose of an axiom in mathematics. The point is that mathematics contains no concept of actual truth. — JeffJo
Yep, you got it! :up:I think I get it now. The proper subset of the infinite set itself has to be infinite.The number of elements in a proper subset B of a finite set A is necessarily less than the number of elements in the set A. n(B) < n(A) so long as A and B are finite. - In other words the fact that the set of even numbers don't contain odd numbers and that the set of natural numbers is the union of odd and even numbers didn't translate into a numerical difference like it does with finite sets. — TheMadFool
I'm not sure what he meant, but a bijection is both an injection and a surjection.I think fishfry said something to the effect that bijection has precedence of injection. Why? — TheMadFool
Well, there might be reason why especially from the historical point of view people would oppose socialism. It hasn't been all dancing on roses and happiness. In my family, two of my great grandfathers were nearly killed by the Red Guard during our War of Independence. They were defined to be the 'class enemy' by the dictatorship of the proletariat, hence the violent side of marxism (and especially Trotskyism) is something really true and not something that "just got understood the wrong way". And my grandfathers fought the Soviets in WW2. Back then the Workers Paradise was intent on annexing my little country. (The other grandfather was a surgeon, so he didn't literally fight).Ok, I'm listening, but the original point I was making that you replied to was about a long term (over a 100 year period) stream of anti socialism dogma. I wasn't really referring to recent developments, but rather that recent developments sit on the top of an edifice of anti socialist dogma and prejudice, Comy', Marxist, Trotskyist. They will let the Comy's in by the back door. — Punshhh
But this is politics 1.0. It's basically quite arrogant not to understand how the other side will take your views. A mainstream party ought to look at what it says.I am aware of Blair's thoughts on this and accept that there is some anti-semitism in the Labour Party, but not as much as claimed by the media. The subtlety of the disitinction between "anti-Israeli foreign policy" sentiment and "anti-Israel" sentiment. Has been exploited by critics and sometimes mistakenly blurred by those being criticised. — Punshhh
I'm not sure if he was your best hope. I put my hope on politicians that take extremely seriously and treat with respect the people who oppose them and think differently. Far too often we just dismiss the opposing views and start to believe our own biased views.My beef in this is that I am anti-Brexit and Corbyn was our best hope in somehow stopping it. — Punshhh
Sure, but above with Blair you have a former leader of the Labour party saying: "The door was locked to those elements with a kind of 'not wellcome' sign on the door. And the truth is now because the leadership is from that tradition, the door is with a wellcome mat. And what's happened is you have had a whole lot of people come in to the Labour Party with these views" Later he says that singling out Israel "seeps into anti-semitism".Tbh when ever I see cries of ‘anti-semitism’ I assume they’re false. The reason being when I’ve looked further they are usually comments taken out of context and/or criticisms of the Israeli government. — I like sushi
Oh the right wing media...is (ghasp) against a labour candidate? And it's ugly?Well the evidence is there in print, the bias and attack of any consideration of socialism by the right wing media. — Punshhh
And could you think of a reason for this? Or is it a huge conspiracy?The magazine Socialist Worker, the only populist left wing paper I know of was desolved in April this year. — Punshhh
But?There is one left leaning mainstream newspaper The Gardian, but this paper gives politically balanced intellectual analysis of politics and is only left leaning by contrast to the right wing papers which predominate. It is widely regarded as having the highest standards of reporting in the UK. — Punshhh
Poison? The only poison has been fed to that metropolitan socialist elite and the younger 'educated' voter. It's their hubris, the idea that some of the previous supporters have been duped, that is the problem it. You have it totally the wrong way., I would add that the drip feeding of anti socialism poison goes right back to the origin of the Labour Party and has become endemic now everywhere except for the metropolitan socialist elite and the younger educated voter. — Punshhh
I think the structural problem is that if you go to war, your objective would be to win it. In truth, that hasn't been at all the objective. Nothing like that. Just fanciful rhetoric to pander the American voter. This is why American wars get so fucked up.Still, the point here is nation-building, not fighting a landlocked war between Pakistani, Saudia Arabian, and Iranian influence. — Wallows
If I remember correctly, some use that as a definition of infinity:but wait, can a set be considered an element of itself??? — John Gill
No.However, we still have to consider fact 2 by which we can determine inequality of cardinality of sets
The set of natural numbers N = {1, 2, 3, 4,...}
The set of even numbers E = {0, 2, 4, 6,...} — TheMadFool
Again no!It's clear that N can be separated into two proper subsets viz. the set of even numbers V = {0, 2, 4, 6,...} and the set of odd numbers, D = {1, 3, 5, 7,...}
Notice how set E has a bijection with set V and set V is a proper subset of set N. If so, then in accordance with fact 2 above, n(E) < n(N) i.e. the set of even numbers is less than the set of natural numbers.
This presents a problem doesn't it? — TheMadFool
Doesn't have to. Enough voters think it was so. Repetition is the way to get lies to work.What if he outright declares that the Mueller enquiry and the impeachment hearings really were a coup attempt and declares a state of emergency? — Wayfarer
Yes, a guy who worked in a movie theatre that Trump visited is sorted to be the best answer.If you’re ever bored read through these Reddit threads. They are anecdotes of people who have worked for him or have met him. If what they say is true he it seems he is a very nice and likeable man, and not the villain people make him out to be. — NOS4A2
How about learning actual math? Set theory in this case. It's easy in our time. Just google it. I'll even give a link here: Well-order. Or here: Well ordered set or Well-ordering principle.What do you mean well ordered? Kindly explain. — TheMadFool
I wouldn't agree on this. Axioms don't give proofs. Perhaps we are just thinking of this a bit differently.And we don't prove existence. Axioms do. — JeffJo
Mathworld WolframAn axiom is a proposition regarded as self-evidently true without proof. The word "axiom" is a slightly archaic synonym for postulate. Compare conjecture or hypothesis, both of which connote apparently true but not self-evident statements.
Now this is great thinking from a fellow PF member, the reason why I participate in this Forum.I have had a horrible thought about Trump - that the impeachment will turn out to be the Coronation of the Emperor. Meaning that, if/when the supine Senate Republicans absolve him of sin, then he has completely untrammelled reign, of the kind that he's behaved as if he's had since elected. I think if that happens we will begin to see the real Trump for the first time. — Wayfarer
Back then the whole thing was dealt differently. As you said, it indeed was a discussion conducted among smart, scientist-type adults. Now it's not.Global warming has been a hot topic of discussion for the last 40 years, conducted among smart, scientist-type adults. Did I hear about global warming in 1980? No. Back then, the burning issue was the ozone hole over the antarctic and diminished ozone in the upper atmosphere elsewhere. — Bitter Crank
